To all whom di may concern: i Be it known that Lrhnnai-rnivr timonnnn, a

subject of Russia, residingatGhelsemin the county of tduffolk and EitateofMassachu- 1 setts, have inventedcertainnew and useful improvements in Cement AApplying na chines, of whicl'r the following is a specie 'lication. i Elhis invention relates to machinesfor applyi ig cement,or other adhesive substance, to a material, such as leather,*for the pur poseof attachment to other material; and

the object of the invention is to provide for makmg such application of the cement, or

other adhesive substance, in a rapid, neat, inexpensive and e'liicient manner.

To accomplish this object, I take a well known type of cementing machine, in which the cementconveying wheel, orroll, is ver:

tically and rotatively mounted in a cement tank and extends through the slotted top of the tank, and attach to the upper face of the top of the tank a device, which partly surrounds and partly covers a portion of the upper part of the cement conveying roll, and which includes a support for the material operated on, a guide for said material,

, a cement guard, and a scraper for removing a surplus cement from the material.

The invention is illustrated by the accompanying drawings, in which: Figure 1 is a sectional view of the tank with the rolls and the device in elevation; Fig. 2 is a plan view of the tank, the lower roll and the device; Fig. 3 is a face view of the rolls partly broken away and showing thedevice in seci 1 I t1on;,h1g. i 18 a front elevatlon of the device; l 5 is a similar view of a modification of the device; Fig. 6 is a plan view of a modification of the device; and Flg. 7 is an elevation of the view shown in Fig. 6.

The cement conveying roll 1, preferably grooved as shown in Fig. 2, is vertically and rotatively mounted in the tank 2 with its lower part immersed in the cement 3 contained therein and itsupper part extending tl'n'ough the slot L111 the top of the tank;

the feed roll 5 being disposed. above the outer portion of the face of the conveying roll; which rolls are here (Fig, 1) conventionally shown, but which, as is well known,

are in practice geared to rotate in opposite R directions as indicated by the arrows at and 7); it being customary also to cushion the feed roll and. to provide a treadle, or similar l'l'lGlllllS, for separating the rolls at the will Specification of Letterslatent. i

t teme s a ne of the operator; none of which features are shown, however, as they are all well known features of these machines and have nothing to do with the prusent inugrovement; the

same being true of the various weii known rat-eaten n a, reset methods of supplying the tank with cement and regulating its movement therein, none oi: which are shown. a a

The invention consists in combining with the elements above described the following elements: (l) The cement guard (3, which stands between the operator and the sideof the cement conveying wheel 1; the flanged top 7 of which extends over a portion of said roll and acts both as a guard and as a support for the material ll, as it travels be tween the rolls: The scraper 8, at the ieft of the operator, over which the material is guided by the operator and which serves .to remove therefrom the surplus cement:

(3) The guide 10, which enables the operator to guide the material as it travels between the rolls in the direction indicated by arrow 0, Fig. 1. These four elements: guard, support, scraper, and guide, are preferably combined in a single member, which is soldered or otherwise attached to the top of the tank as above described. The guard 6 may be formed as shown in Fig. l, or as shown in Fig. 5, or its form may be varied as desired; the opposite arm 9 of the device may be of any desired length and may be shaped as in Fig. 6 to furnish the guide 10 along which the material travels when being operated on.

I claim 1. In a cementing machine of the character described, in combination, a tank having a slotted top; a cement conveying roll vertically and rotatively mounted therein and extending through the top thereof; and a combined cement guard. and work support attached to the top of the tank adjacent to and partly covering the top of the conveying roll.
